First, they're an organ in your body. Second, your lungs help you breathe and your heart keeps your body going. Without them, you wouldn't be able to live. So the similarity of the lungs and the heart is that it helps you live, or rather you need these to live.
The heart makes a "lub-dub" sound. The first is when the AV valves close and the ventricles are filled. The second is when the semi-lunar vlaves close and the blood is sent to the lungs, or to the rest of the body.
